Answer 3

my aunt told me how to do it, but the teacher says it is wrong
and when I asked someone else they got same answer as my aunt

Answer 4

i do not understand how to multiply and divide fractions

Answer 5

umm how did ur aunt do it?

Answer 6

adding n suctracting them she would find common denominators and then simplify but my teacher says my aunt is wrong

Answer 7

ah ok, well, multiplying is pretty easy: you just multiple the top number of each fraction and the bottom number of each fraction

Answer 8

like this problem 5 3/4 divided by 1 2/3

Answer 9

ah ok, so for that problem you can convert it to a non-mixed fraction

Answer 10

let me re write that one
5 3/4 \[\div\] 1 2/3

Answer 11

so 5 3/4 means 5 whole parts of 4 (20) + 3 parts of 4

Answer 12

that is, 20/4 (since 20/4 is 5) + 3/4 = 23/4

Answer 13

how do I do that?

Answer 14

1 2/3 is saying "I have one set of 3's, and then 2 more"

Answer 15

so that means I have 1*3/3 + 2/3 = 5/3

Answer 16

now when you divide fractions, it's the same thing as multiplying by 1/(originalfraction), which basically means you multiply by the inverse of the fraction by flipping the top and bottom

Answer 17

oh ok
see my teacher does not explain it that thorough

Answer 18

so 23/4 divided by 5/3 = 23/4 * 3/5 (I just flipped the 5 and the 3) = (23*3)/(5*4) = 69/20

Answer 19
